DISCUSSION AND OUTLOOK
----------------------
At 800 AM AST (1200 UTC), the center of Hurricane Lorenzo was located near latitude 43.0 North, longitude 28.0 West. Lorenzo is moving toward the northeast near 43 mph (69 km/h). A continued fast motion toward the northeast is expected through Thursday morning. The cyclone is forecast to slow down and turn eastward by Thursday night. On the forecast track, the center of Lorenzo will continue moving away from the Azores today, and move near Ireland Thursday evening.
Maximum sustained winds are near 85 mph (140 km/h) with higher gusts. Only slow weakening is forecast during the next 48 hours, and Lorenzo is expected to be a strong extratropical cyclone when it approaches Ireland Thursday afternoon and evening.
Hurricane-force winds extend outward up to 150 miles (240 km) from the center and tropical-storm-force winds extend outward up to 390 miles (630 km).
As Lorenzo passed near the western Azores earlier this morning, a sustained wind of 74 mph (119 km/h) with a gust to 101 mph (163 km/h) was reported on Corvo Island. A wind gust of 90 mph (145 km/h) was observed on Faial Island, and a gust to 88 mph (142 km/h) was reported on Flores Island.
The estimated minimum central pressure is 960 mb (28.35 inches).
RAINFALL: Lorenzo is expected to produce additional rain accumulations of less than 1 inch (25 mm) through this morning. Isolated storm total amounts of 2 inches (50 mm) are possible in the western Azores.
SURF: Swells generated by Lorenzo have spread across much of the North Atlantic basin and are affecting the east coast of the United States, Atlantic Canada, the Bahamas, portions of the Greater and Lesser Antilles, the Azores, and portions of the coast of Europe.
These swells are likely to cause life-threatening surf and rip current conditions.
